-v0.2.3
-- Initially published version
-
-v0.2.4
-- Fixed closing of file descriptor of event loop's semaphore on exec
-- Fixed interrupt handling when polling
-- Improved tutorial
-- Fixed issue with googlemock
-- Added object proxy factory overload that takes unique_ptr to a connection
-- Workaround: Clang compilation error when compiling sdbus::Struct (seems like an issue of Clang)
-
-v0.2.5
-- Real fix for issue with sdbus::Struct inherited constructors
-- Little code refactorings and improvements
-
-v0.2.6
-- Fixed memory leak in Message copy operations
-
-v0.3.0
-- Introduced support for asynchronous server-side methods
-- Refactored the concept of Message into distinctive concrete message types
-- As this release comes with breaking API changes:
-    * if you're using lower-level API, please rename 'Message' to whatever concrete message type (MethodCall, MethodReply, Signal) is needed there,
-    * if you're using higher-level API, please re-compile and re-link your application against sdbus-c++,
-    * if you're using generated stub headers, please re-compile and re-link your application against sdbus-c++.
-
-v0.3.1
-- Fixed hogging the CPU by server with async methods (issue #15)
-
-v0.3.2
-- Switched from autotools to CMake build system
-
-v0.3.3
-- Minor fixes in tutorial examples
-- Add comment on threading traits of Variant and its const methods
-- Fix broken invariant of const Variant::peekValueType() method
-
-v0.4.0
-- Introduce support and implementation of common D-Bus annotations
-- Remove hard-coded warning-related compiler options from the build system
-
-v0.4.1
-- Change constexpr member into a getter method to be compatible across odr-usage rules of various compiler versions
